Manufacturing Quality Control of 2-NAPHTHYLMAGNESIUM BROMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (C10H7MgBr content) | Acid-Base Titration with Standardized HCl | Quantifies active Grignard species by hydrolysis followed by titration of liberated base with standardized acid. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Residual Solvent (THF) | Gas Chromatography (GC-FID) | Separates and quantifies tetrahydrofuran using flame ionization detection against calibrated standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace metal impurities by plasma ionization and mass spectrometric quantification at isotopic masses. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Measures Cl- ions via silver nitrate titration monitored by silver electrode potential change. |
| Free Bromine | Redox Titration with Na2S2O3 | Quantifies elemental bromine by iodometric liberation followed by thiosulfate titration. |
| Appearance and Color | Visual Inspection and APHA Color Scale | Assesses physical state, clarity, and color intensity by comparison to platinum-cobalt standard solutions. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
| pH of Aqueous Hydrolysate | pH Meter Measurement | Measures hydrogen ion activity in diluted, hydrolyzed sample after quenching with aqueous buffer. |
| Non-Volatile Residue | Gravimetric Analysis | Quantifies insoluble or non-volatile contaminants by evaporation and weighing of residue after drying. |
| Stability (peroxide formation) | Iodometric Test | Detects peroxides formed upon aging by iodide oxidation and subsequent starch-iodine colorimetric assessment. |
| Organic Impurities (e.g., 2-bromonaphthalene) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies related organic compounds via retention time and characteristic mass fragmentation patterns. |
